I am thinking of doing some more major work on the 4 wheel system of
my explorer, but I am trying to figure out what I have, and have not
found positive info on the web yet.

Anyway, some info: I have the '93 4D 4WD exp, the EB model. The EB
also means that I have the tow package, so I have the 3.73 gears in
the back.

Now, I read somewhere that if you have the 3.73 in the back, that it
is a limited slip diff. in the back. Part of the reason I am doing
this is that the Exp's 4wd is not very good in _really_ ugly stuff,
and I have gotten stuck in not very difficult amounts of snow becuase
of the differentials.

So, does that mean that I have ht elimited slip in the back? because
I had heard that those can wear down after a while, and thne act like
an open diff, and wondering if that is what may be happening. (I
know I could take the diff. apart, but I am not wild about doing that
if I don't have to.)

So, If I have the limited slip in the back, that is good, and I only
need to worry about the front. I was thinking of putting lockers in
the front, and since this truck will still see lots of pavement use,
I was thinking of the ARB Air lockers. anyone use these and like or
dislike them? or any other suggestions? That way I could completely
unlock them when I don't need and save on mileage and stuff.

Another question, in a slightly different direction: what is there
between the front and the rear gearbox as far as a differential or
connection? I am wondering what it would be like to also make it so
that I have more of a "natural" full-time four wheel drive. Right
now, in four wheel drive I get the "hopping" from when going around
turns. Since both the front and the rear diffs seem to be mostly
open, then I am guess it is the binding _between_ the front and the
back, and wondering if it is just a straight connection (Which is my
guess).

If it is just a direct connection, is it possible to put something
in? like a thrid diff in the middle, or a viscous coupling or any of
those other wonderful things? This is more of making it so that I
can do full time 4wd on pavement and stuff more comfortably, the
earlier questions are in regards to off road/sloppy stuff.

Is that possible, or is it a lost cause with the explorer's 4wd system? :)

just trying to get an idea of what I have and what I can do with it.

My '96 Ranger with the 3.0 engine and 99K miles on it had trouble starting
for the first time ever this morning. I turned the key and the engine
'started to start'. As soon as I let go of the key the engine immediately
died as if there were no spark. This happened twice. On the third try it
started normally. Any ideas? The Check Engine light has been on for over a
year now, but the truck runs great and gets its normal 18-20 miles per gallon.

Are you sure about this? Have you actually seen this happen or have
you just heard about this? I would think that most of the teflon
would be removed during the oil change and that any amounts of teflon
would just be "trace" anyway.

The point about teflon is that it does not easily bond with other
substances (how "they" get teflon to bond with cookware would be very
interesting for me to find out). It is very "slippery" and I would
actually think it would be more useful if engine parts were actually
coated with it in order to improve heat dissipation as well as slow
down wear. (But do the big car manufacturers want to sell cars whose
engines don't wear out as quickly?)

I agree with the assessment with Mobil 1. I have heard only good
things from others who own performance cars as well. I have never
heard anything negative about it or seen any problems caused by it.

However, if you have an older vehicle, it may not be wise for you to
start using it if you don't want your vehicle to drip oil and stain
the driveway. Over time a vehicle's gaskets start to harden up and
while they may not leak with regular dino oil, synthetic oils have
smaller molecules and as a result may leak. If you don't care about
drips, then I say go ahead and use it on an older vehicle.

I think it was Briggs and stratton did a test of long term useage of teflon
containing additives... they found the oil passages with large deposits
that plugged them. Dupont also states that their teflon product has no
place in an engine oil.

For those of you with 96 and newer vehicles with OBD-II that want to see
what the engine is doing, if you have a laptop computer, Alex Peper sells a
scantool with cable/software that does GM/Ford/Chrysler for 120.00 (single
make) or 162.00 for all 3.
Works great as I've been playing with mine all weekend!

Alex has a scantool that runs $120.00 for a single interface (ford, GM, or
chrysler) and $162.00 for all 3 in one.
